VServer can’t ping localhost

Currently having an issue with “openxchange” running inside a VServer – guest instance of Fedora Core 3. Issues were as follows:

ldap and other services :- referring to localhost but it (127.0.0.1) is unreachable – no loopback interface. Rather than working out WHY there was/is no loopback interface, I modified /etc/hosts so that 127.0.0.1 was altered to the IP address of the VServer’s IP ie:
127.0.0.1 severname localhost localhost.localdomain
//became//
192.168.0.5 servername localhost localhost.localdomain

this left a few issues with some services: httpd (apache2) would no longer start – the fix was to insert the ServerName paramater into /etc/httpd/conf/httpd.conf as follows
ServerName 192.168.0.5

postgresql was then unhappy with life due to security reasons – so we added the following line to /var/lib/pgsql/data/pg_hba.conf
local all all trust
host all all 127.0.0.1 255.255.255.255 trust
host all all 192.168.0.5 255.255.255.255 trust


**Please note – the ip addresses used in this example are NOT real IP’s on my network but used to make reading this solution/fix slightly better.

My solution is probably NOT the way to go about it, but hey, it works and its “good enough” for now.
